May I just clarify - is it just the bird in photos 1636-37 that you're questioning, or all of them? To be honest as a British birder I've little enough experience of pure normal-looking birds let alone intermediate-looking ones (hybrid or not) so am very much relying on expertise of North American birders.Dave Appletonhttps://www.blogger.com/profile/15077880196249359409noreply@blogger.comtag:blogger.com,1999:blog-8553998527275861247.post-42155233845659661242019-05-14T14:33:17.717+01:002019-05-14T14:33:17.717+01:00I have a photo of a bird from Cheyenne County KS t...I have a photo of a bird from Cheyenne County KS that I wonder if it could be a hybrid.

Yes, the supercilium is typically more rufousy on SY males than on this individual and others that I found online (although in none of the photos are they entirely white). Similarly, the entire underparts are typically more rufousy, as well, although one can still see dabs of that color on the sides, mid-belly, and vent on this bird. In photos of more clearcut male hybrids I've uncovered, the lower underparts tend to be more starkly white. More significantly, I have yet to see a photographed hybrid with a strip of yellow projecting down the central belly. In those hybrid photos I've seen, that stripe is always the same rufousy color as the breast, which would apparently indicate RBGR influence. Lastly, the bill color looks entirely appropriate for a BHGR. So, I just don't see that necessary degree of intermediacy indicative of a hybrid.
